The incident began about 3 p.m. Tuesday when deputies received reports of a "male subject" walking through Santa Rosa carrying a gun. Police located the subject, identified by the San Francisco Chronicle as Andy Lopez, carrying what appeared to be an assault rifle. Deputies ordered Lopez to drop the weapon. It wasn't immediately clear what prompted officers to open fire but they did, striking Lopez multiple times.
The teen was declared dead at the scene.
After opening fire, officers discovered the assault rifle, while real looking, was plastic. Lopez was also found to have a plastic handgun tucked into his pants.
The Chronicle said the deputies involved have been placed on administrative leave pending the outcome of an investigation by the department and the Sonoma County district attorney's office -- standard practice in police shootings.
The incident was the third time in 24 hours a law enforcement officer has fatally shot someone in the Bay area. Union City police shot and killed a parolee armed with a pipe Monday night. Early Tuesday, a car thief was killed by a San Bruno officer after the suspect pointed the car at the officer.
